Activity summary

Prorenin also known as angiotensinogenase is a precursor form of renin. This protein plays a vital role in the renin-angiotensin system (RAS) which regulates blood pressure and electrolyte balance. Prorenin is primarily synthesized in the juxtaglomerular cells of the kidney and possesses a molecular weight of approximately 40 kDa. It exists in an inactive form until it is cleaved to form active renin. It moves through the bloodstream to reach target tissues.

Biological function summary

Prorenin initiates the conversion of angiotensinogen to angiotensin I an important step in the RAS. In its inactive form prorenin circulates throughout the body but remains ready for activation. The activation involves a non-proteolytic conformational change or proteolytic cleavage within the kidneys. Prorenin may exist as part of a complex with the (pro)renin receptor which influences various physiological processes beyond blood pressure regulation.

Pathways

This precursor functions as an important regulator within the renin-angiotensin system. Prorenin by forming renin is directly involved with the conversion of angiotensinogen into angiotensin I. This initial step leads to further pathways that construct angiotensin II a potent vasoconstrictor affecting the vascular system. The activity of angiotensin II ties closely to the actions of the enzyme angiotensin-converting enzyme (ACE) which transforms angiotensin I to angiotensin II.

Associated diseases and disorders

Prorenin's activation links strongly to conditions such as hypertension and diabetic nephropathy. Elevated prorenin levels have been observed in individuals with hypertension indicating its central role in this disorder. Furthermore its interaction with the (pro)renin receptor contributes to the progression of renal disease in diabetes-related nephropathy. The relationship among prorenin renin and the (pro)renin receptor provides significant implications for therapeutic strategies targeting these conditions.
